O y = (x - 1)2 + 1
y = (x - 1)2 - 1
y = (x + 1)2 + 1
· y = (x + 1)2 - 1
Answer:
y = (x + 1)² - 1
Step-by-step explanation:
The equation of a parabola in vertex form is:
y = a(x - h)² + k
where the vertex is located at (h,k). Replacing with vertex at (-1, -1) we get:
y = a(x - (-1))² + (-1)
y = a(x + 1)² - 1
The only option with vertex at (-1, -1) is y = (x + 1)² - 1 (where a = 1)
Answer:
d
Step-by-step explanation:
The required, Mrs. Simpson's speed was 42 miles per hour.
Speed is defined as when an object is in motion, the distance covered by that object per unit of time is called speed.
Here,
To find the speed (or velocity) in miles per hour, we need to divide the distance traveled (in miles) by the time taken (in hours).
Mrs. Simpson drove 105 miles in 2 1/2 hours, which can be written as:
Time taken = 2.5 hours
Distance traveled = 105 miles
Speed = Distance / Time
Speed = 105 miles / 2.5 hours
To divide 105 by 2.5, we can convert the mixed number 2 1/2 to an improper fraction:
2 1/2 = 5/2
Then we can divide:
Speed = 105 miles / (5/2) hours
Speed = 105 miles * (2/5) hours
Speed = 42 miles/hour
Therefore, Mrs. Simpson's speed was 42 miles per hour.

Answer:
x=14.5
Step-by-step explanation:
50.48=-22.02+5x
5x=50.48-(-22.02)
5x=50.48+22.02
5x=72.5
x=72.5/5
x=14.5
3w minus w is 2w, +4w is 6w. subtract 15 w both sides of the equation to get 33 on one side, and 9w on the other side. divide 9 on both sides, and the nswer is 3 and 2/3.
First, start by adding like variables on the same side of the equal sign
Next, subtract 15w from both sides to get like terms on the same side
Finally, divide -9 on both sides to get the variable alone
72%=72/100=36/50=18/25
have a good day, I hope it helps
Answer:
-1/6
Step-by-step explanation:
flip the slope
becomes
now the slope is going down so it becomes negative
= -1/6
